Science Project - Tub Volume

Steps taken:

1 - we measured one gallon in our medium sized container using a 1-cup measuring cup.

2 - we measured three gallons in our large sized container using the one gallon mark in our medium sized container.

3 - we measured the volume of the tub up to the bottom of the drain valve plate using the large container.

It took 10 of the three-gallon dumps to fill the tub. 30 gallons.
